This invention relates to trucks, skids and the like. A

One of the objects of this-invention is to provide a truck or skid ofimproved construction of the semi-live or semi-skld type.

Another object is to provide a truck or y skid body or platformconstruction which will have the maximum of strength -for the minimum ofmaterial, and which will be cheap and simple to manufacture.

Another obJect is ,to provide a truck or skid platform adapted to beembodied in trucks or skids of different types and usable n skilled inthe art to for different purposes.

Another object is to provide a truck or skid latform formed from asingle sheet ot metal) cut to shape as a, blank and folded or bent atits edges to form a finished reinfor-ced bed or platform.

Another object-is to provide a platform formed from a single sheet ofmetal and blanked to suitable shape and bent or folded at the edges toform a truck or skid form body, the reinforcements along the side of thelongitudinal edges of the platform being of channel, angle tubular orthe iike form, to provide great strength as well as lnishecl appearance.y

@ther objects will be apparent to those which my invention pertains.

plat- Y 1 a truck bed or body of platform type formed'from a sin lesheet of metal preferably steel. The eet metal is first blanked out to arectangularly notched pattern indicated by the broken line, outline 2having the blank are also bent downwardly to form side portions 8--8 andare then bent inwardly, to form flanges 9--9, thus makin side portions 8of inwardly open channe form.

At the corners of the platform, the end portions 't have vertical edges10 lying-adjacent to vertical edges 11 of the side por tions 8 and theseedges are preferably welded to each other by Welding material asindicated et 12-12.

lt will be noted that the longitudinal extreme ends ci the anges 9 abutagainst the inner faces of the end portions 7 adjacent to the ends ofthe latter at each corner of the bed and the danges 9 and the endportions Z' may at theseabutting points be welded together if desired.The truck bed or platform thus constructed, although made kof a singlesheet of relatively thin Vmetal is seen to give the appearance of a bodyof considerable vertical thickness when viewed from the outside; and theends thereof are reinforced against bending or yielding under loadswhich may be placed upon the platform b theivertical end portions; andthe longitu inally extending side portions of the platform are stillmore strongly rein forced to carry loads by being given channel form;and by means of the welded portions referred to, all parts of theplatform are rigidly and permanently oined together ICapd renderedadditionally strong and duraln the form of my invention illustrated inFigs. 1, 2 and 3 the platform or bed is shown applied to the type'otruck known as semi-live or semi-skid. At each end of the bed orplatform l and enclosed between the side 'and end portions 8 and 7 aresills 13 and 13 referabl of wood. Theu per ilat faces oft e sills lleagainst. the un er surface of the central portion 6 of the latform, thelongitudinal end `edges. of t e sills abut against the inner faces ofthe end portions 7, and the transverse ends of the sills abut againstthe inner faces of the side portions 8, and adjacent to their ends, theunder surfaces of the sills lieu on the flanges 9.

At one end of the p atform or bed is provided a pair of supportingwheels 14 mounted in yokes 15, which'are bolted by bolts 16, 16 and 17,17 to the platform. The bolts 16 pass through flanges 18 of the yokes 15and through the flanges 9 and through the sill 13 and top portion 6 ofthe truck platform, and the bolts 17 pass through flanges 18 of theyokes 15, and through spacing washers 19, sill 13 and top portion 6 ofthe platform. The other end of the truck is provided with a pair of skidbrackets 20, comprising each a foot 21 adapted to rest on the floor andfront and rear bracing legs 22, 22 terminating upwardly in attachingflanges 23-23, and secured to the underside of the bed by bolts 24-24passing through the flanges 23, through the flanges 9 of the bed,through the sill 13 and through the top portion 6 of the platform. Inthe front end of the truck and on its longitudinal axis is a couplingdevice 28 comprising a plate 25 preferably bolted to the underside ofthe bed or to the underside of the sill 13 in any suitable manner as bybolts 26 passing through the plate 25 and through sill 13 and throughtop portion 6 of the bed, and having in its forward end a downwardlyprojecting pin or other suitable coupling arrangements 27.

By means of the foregoingconstruction the truck may be ymoved about fromplace to place by means of an auxiliary wheeled device not shown butknown in the art which may be coupled to the coupling element 27 formside portions 30 and flanges 31 are again ,bent upwardly as at 32,outwardly as at 33, and upwardly as at 34, thus 'providing aside portionfor the platform of a double thichiess angle section. The end section ,7may be welded to the longitudinal ends of the Side portionsin the formof Fig. 4 simi larly as in connection with the form of Figs.

1, 2 and 3.

In the form of my invention shown in Fig. 5 vthe 'side edges of'theblank, besides being bent downwardly as at 40 and inwardly as in 41, arebent upwardly-as at 42, thus providing side portions of thetruck body ofbox, or tubular section as shown in Fig. 5,'

4, the ends of the sills may abut against the upturned portion 34 or 32,or 34 and 32.

In Figs. 1, 2 and 3 my invention is shown as applied to a semi-livetruck or skid; but it will be apparent that thev improved plat-v form orbed thereof and which forms one l of the essential features of myinvention ma -be embodied in 'skids of the dead Atype suc as, forexample, a skid having three or four i skid brackets 20 and having nowheels or embodied in a platform truck of the live type having a numberof wheels either castering or non-castering.. I thus show. and describethree forms of platform or body adapted to be embodied in platform skidsor the like. It will be understood that in the forms ofmy inventionshown in Figs. 4 and 5 the truck or skid platform or body thereillustrated may be combined with other truck or lskid elements to formtherewith a wheeled or other type of truck or skid, and that the form ofmy invention shown in Figs. 1 to 3 may be embodied with different othertruck or skid elements than shown and described to form a truck or skid.

My invention is not limited to the exact detalls of construction shownand described. Manyy modifications and changes therein may be made otherthan those shown such as other sectional forms of the horizontal sideportions of the truck, etc. without departing from the spirit of myinvention or sacrificing its advantages.
